The invention discloses a wind power tower flange support anti-deformation method and device. The device comprises a first supporting plate, a first connecting rod, a connecting piece, a second connecting rod and a second supporting plate. The method comprises the following steps: step 1, according to the weight of a tower, the size and position of a bolt hole of a tower flange and the inner diameter of the flange, selecting all parts of the wind power tower flange support anti-deformation device; secondly, the supporting plates and the connecting rods are firmly welded in a welding mode; thirdly, before the tower is transferred or loaded, the device is installed on a tower flange in advance, and it is guaranteed that the device is located in the diameter direction of the tower flange and a connecting piece is located on the lower portion during installation; fourthly, when the tower is transferred or loaded, the tower is supported by the lifting belts, the connecting pieces are adjusted immediately, and the device is tightened; and 5, when the wind power tower is transported to a wind field for hoisting, the tower is supported by a hoisting belt, the connecting piece is loosened, the first bolt and the second bolt are dismounted, then the device is wholly dismounted, and then the hoisting operation of the tower is carried out.
Description
technical field [0001] The invention belongs to the technical field of wind power generation, and in particular relates to a method and a device for reverse deformation of a wind power tower flange support. Background technique [0002] With the rapid development of the wind power generation industry, the trend of large-scale wind turbines is becoming more and more obvious, and the diameter of the supporting towers is increasing. At the same time, with the advent of the wind power generation parity era and the development of wind power flexible tower technology, the design unit is to control costs and continuously optimize the thickness of the steel plate and flange of the tower body, which leads to the further expansion of the deformation of the tower during storage and transportation. . In the process of hoisting the wind turbine, a lot of manpower, material and mechanical calibration have to be spent. At the same time, after mechanical correction, although the smooth ho...
